Hey I Want To Call Complete Data Of Name Column From Database In Asp.Net C#

Your question is not clear. Anyway I'm writing an example to read the particular column value from DB and bind with DataGridView.

SqlConnection conn = new SqlConnection("Data Source=;Initial Catalog=;Persist Security Info=True;User ID=;Password=");
conn.Open();

String query="Select [ColumnName] from [table1]";

SqlDataAdapter da = new SqlDataAdapter(query, conn);
DataSet ds = new DataSet();
da.Fill(ds);
this.GridView1.DataSource = ds.Tables[0];
this.GridView1.DataBind();

conn.Close();
